I'm worry

I'm worry about my brother. Why? I'm hoping he doesn't do drugs and act up when he gets out. I'm going to be by myself. No one here to help me with him. He doesn't listen to me. I could scream it goes into one ear and out the other. The only time he nice is when he needs money. If I don't give him  money he try to steal from me. The last time he was really high he threw two bottles at me. I hope he learns from the mistake he has done while he been in jail.  He never change when he was in there last time. Now I'm very worry!!
